Configuring the Trading Environment

Overview

After installing the TT Gateway, you must perform the following
procedures:

Stop all TT-related services.

Configure Exchange-flavorhostinfo.cfg (referred
to throughout simply as the hostinfo.cfg file)
and edit the ttchron.ini file.

The LSE Gateway uses pMerge to populate product and tick
tables.

Configure time zone settings in aconfig_local.xml. Do
not modify any other aconfig default settings without first contacting
your local TAM.

Stopping TT-Related Services

Before configuring
the TT Gateway, you must stop all TT-related services.

To stop Services:

From the Start menu, point
to Settings,
and click Control Panel.

The Control Panel opens.

Double-click Administrative
Tools.

The Administrative Tools window
displays.

Double-click Services.

The Services window displays.

Scroll through the Services box to locate
TT Chron.

Right-click TT
Chron, and then click Stop.

If there are any other TT Services running, you
must stop them as well. One at a time, right-click the TT service,
and then click Stop.

After you have stopped all TT services, close
the Services and Administrative Tools windows.

TTChron.ini

Located
in <root drive>:ttconfig,
all services in the ttchron.ini file
must be set with the correct startup and shutdown times. For information
and restrictions on configuring ttchron.ini,
refer to the TT Gateway
Architecture SAM Version 7.X.

Note

On the gateway, Order Routers are threads
managed by the Order Server. The ttchron.ini file
does not have an Order Router section.

Warning

The following warnings apply to the
gateway startup and the use of ttchron.ini:

You must set the Order Server to start up
on Sunday before the LSE. If the Order Server cannot startup
after a failure (i.e., it has been already running that week), you
must start it up using the -r command line option.

Leave TTChron running after installing and configuring
the LSE Gateway.

To edit the ttchron.ini file:

Verify that the Price Server start
time is set to 05:00 EST.

This setting ensures
that the LSE Gateway captures the correct product listings. If the
Price Server starts after the exchange starts broadcasting products,
the LSE Gateway can have incorrect products listings.

Verify that the daily Order Server stop time
is set to 16:45 EST.

Use this information to determine the correct
startup times for all LSE Gateway processes. Since the LSE can
change its trading hours at any time, specific startup times are
not included in this document. The times provided in the ttchron.ini file are
representative of the current exchange startup times. Unless otherwise
informed by TT or LSE, do not change these times.

Note

Call the CSC or your TAMs for correct
startup times to use in ttchron.ini.

pMerge

The LSE Gateway installs
with the pMerge executable. During installation, this executable
runs automatically to set up and configure the LSE’s product
and tick tables that the TT Gateway requires. Additionally, when
you upgrade a LSE Gateway, pMerge.exe runs
automatically to merge pre-existing product tables with any product
tables distributed with the new TT Gateway software.
